Construction
Rainwater storage tank pump in block design with radial impellers as multi-stage hydraulics.
Single-phase or three-phase AC motor with sheath flow cooling. The motor is cooled by the pumped medium. The single-phase AC motor is equipped with a self-switching thermal motor protection.
The motor itself is dry. Sealing is provided on the motor and medium side by two mechanical seals. Between both mechanical seals is an oil barrier chamber. The oil barrier chamber is filled with white oil and absorbs any leakage through the medium-side seal.
Connection cable with attached plug.
